Bieber was first snapped at Jenner’s birthday party wearing a white and red polka dot De La Val Gracia mini dress and what appeared to be a pair of Prada leather thong sandals as she sat on a bench on a patio holding a glass of red wine.

The Kylie Cosmetics founder took to her Instagram Stories over the weekend to share a look at her intimate bash.

Ahead of her 28th birthday, Kylie Jenner shared a series of photos enjoying a glass of wine in the sunshine while wearing a brown bikini top.
